, this will just have 2 points to become the singularity, and the fixed point must be in these 2 points;4. In this way $T \cup m$ is a picture with Oralu, short-cutting method to turn Oralu into Hamilton Road.This algorithm $k \in \{0, 1\}$ is a 1.5 approximation algorithm. The following is proof.$k = 0$The proof thought is similar to the TSP. Assuming a $2t$ singularity on the optimal solution, it can be split into two matches: 1-2, 3-4, ..., (

BeautifulSoup is a tool for parsing crawled content, and its find and Find_all methods are useful. And after parsing, it will form a tree structure, for the Web page form a similar to the JSON format of the Key-value, it is easier and more convenient for the content of the Web page operation.　　Download the library without much to say, using the python pip, directly inside the cmd execute pip install BeautifulSoup can　　First copy the document description, the code is copied over, as follows fromB

The programming implementation input any point coordinates (x, y), output the corresponding number, or enter any number, output the coordinates of the number.Analysis: The law can be seen, the problem is how to use it.

Operation steps:UEFI is the "Unified Extensible Firmware Interface" that replaces the traditional BIOS. MBR is the traditional partition table type, the biggest disadvantage is not to support the capacity of more than 2T hard disk. GPT makes up the disadvantage of MBR, which supports up to 18EB hard disks and is a UEFI-based disk partitioning scheme.MBR is currently supported on all Windows systems, and GPT is supported only by 64-bit systems.

+2 = 2 (3k+2), 6k+3 = 3 (2k+1), 6k+4 = 2 (3k+2) are composite, and then remove 6k itself, Prime numbers greater than or equal to 5 can therefore be represented as 6k+1 and 6k+5 (when x is greater than or equal to 6 o'clock, 6k+5 and 6k-1 can represent the same number).Mathematical proofs Prime number x is greater than or equal to 5, then it must not be a multiple of 3, nor a multiple of 2. If a natural number is not a multiple of 3, there are two cases, set x=3p+1 or x=3p+2 (p>1)
